What was linked to was a final ink descriptor file that the installer script uses to create the .quad file. YOu just need to put that in the applications/quadtonerip/profiles/3800-UC folder (the same one with the install script. However, if you try to install that profile you will get the "not constantly increasing error" because the L* values in the 51 step target are too close together—these ones specifically: 5.92 5.86. I struggled with the same thing when I first started creating profile way back when...
It is better to use the 21-step target (with multiple measurements to average out any errors in the readings) to keep the L* far enough apart to not throw that error (the 21x4 random is a good one) . I use an average of several readings from the 51 step target to check for linearity and to create ICC profiles.
Hope that clears it up a little..
